TO ALL WHOM IT MAY CONCERN: l

Be it known that I, ALBERT F. ALLEN, of Providence, in the county ofProvidencejand State of Rhode Island, have'invented a new-and improvedHose-Coupling; and'I do hereby declare that the following is afull,-

clear, and ex'act description thereof, which will enable those skilledinthe art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure l represents a side view partly in section ofmy.improvedhose-coupling. A

Figure 2. is a transverse sectional view of the same. the plane ofsection being indicated by the line :v te, fig. 1.

Similar letters of reference-indicate corresponding parts.

Thisiinvention relates .to a new device. by which the water canbe easilydischarged from hose,`and by which firemen will be better ena-bled tocarry such emptied hose upladders or along the ground or oors. Theinvention consists in the use of a. perforated sleeve, which is fittedaronnd'the perforated cylindrical portion of a hosecoupling in such amanner that the holes in the coupling can be completely closed by thesaid sleeve, when -the hose can be used in the ordinary manner; but whenit is desired to quieklyinterrupt the flowing of the water in thchosewithout stopping the working of the engine the holes in the coupling canbe at once opened by a.

Short turn of the sleeve. The upper end of the'hose will then at once becompletely emptied; thereby the said hose will be lightened and can becarried with facility to any desired place. By another short turn of thesleeve the water can be conducted into the hose again when theno'zzle'is brought tothe required place and position.

A represents the cylindrical portion of Aa metallic coupling of suitableconstruction. Its outside should be made slightly conical, taperingtoward the free end of the cylinder. B is the opposite (female) portionof the coupling, which is screwed or otherwise secured to the cylinderThe cylinder A is perforated by four, more or less, holes. C is a sleevelitting well around the cylinder, being nia-de somewhat conical insidein accordance` with the shape of the'cylinder. The sleeve hasholes-which correspond to those in the cylinder. It is shorter than thecylinder, the thinner end of which is provided with a serew-thread,.uponwhich two nuts a bare arranged, by which the sleeve can 4be forced uptoward the wider 'end of the cylinder to lmake a. tight tit, It

will. be easily understood that by means of-a wrench or otherwise thesleeve can be turn'cd so as to close the` holes in the cylinder A', orso asto open the same, the latter position heilig shown in the drawings.When the holes are thus opened the water will be prevented from flowingnp to the nozzle, and' will escape through the holes. When the holes areclosed the hose will operate in the ordinary manner.

I claim as new, and desire to secure by vllictters Patent- 1. Soarranging n hose-coupling that the flow of water towarilthe nozzle canbe instantly stopped or resumed without interrupting the working of theengine, substantially :is and for the purpose herein shown anddescribed. 2. The perforated sleeve C, ia combination with theperforated cylinderA and nuts-a and b, all made and operatingsubstantially as and for the purpose herein shown and described. i
